There are many services that offer "real-time stock quotes" on the 'net, however, most or all of these are attached to some kind of elaborate charting and analysis software. I would like to do my own perl-based charting and analysis, and would appreciate some help in locating a suitable real-time stock price feed. (Not necessarily a free one!)

I am entirely capable of stripping such data from a streaming web page or other feed (probably with a regex!). One likely suspect is Yahoo! real-time quote service, which _looks like_ a javascript applet fed by a data stream, which probably would be fine.

Many thanks
